Abstract: A method performed by a controller of an electric motor, including generating control parameters, the step of generating control parameters selected from: inputting a given reference torque (Tref) and a speed command to a torque generation lookup table (LUT) such that the step of generating the control parameters includes the torque generation lookup table at the given reference torque and the speed command; or utilizing an analytical model that includes one or more analytical equations or one or more functions; inputting the control parameters to a DC-link current ripple, torque ripple, and radial force ripple minimization lookup table; inputting position to the DC-link current ripple, torque ripple, and radial force ripple minimization lookup table; generating a reference current profile from the DC-link current ripple, torque ripple, and radial force ripple minimization lookup table; and inputting the reference current profile to the electric motor. Additional methods are disclosed.

Abstract: A solid-state circuit breaker may include power modules, gate drives, a current sensor, and a controller. Each power module may include two back-to-back MOSFETs with body diodes. The MOSFETs may have opposite orientations and a common source connection within the power module. The current sensor may detect current, and the controller may determine whether the current exceeds a predetermined threshold. When the current exceeds the predetermined threshold, the controller may transmit a signal to each gate drive to cause each gate drive to output a signal to the back-to-back MOSFETs such that the electrical current through the solid-state circuit breaker is blocked in both directions.
